v0.1.35 is the app update. It does not change consensus, proof of work, supply, rewards, addresses or ASERT.
The wallet now uses the full desktop window on Windows, Mac and Linux, with the same clearer setup, receive, send, activity, backup and small-payment cleanup flow on Android. Existing wallet files and addresses still work.
Use the btc09-wallet-* files for a simple wallet. Use the other five BTC09 files if you want the full node, CPU miner or command line.
Windows and macOS are verified unsigned community builds, so those systems will show an unknown-publisher warning. Android is signed with the same project key as v0.1.34. The iPhone build passes simulator tests but is not included because there is no durable free public install route.
v0.1.34 nodes remain consensus-compatible. Back up your wallet before upgrading and verify your download against SHA256SUMS.
